Question

Ok I kinda get it but I’m not every sure

Answer 1

Answer:

Sara: I can tell from the table that the y-intercept will be the point (0,4) not   (-2, 0).

Darrell: Since the b-values go up by 8 each time, I know that the slope of the line has to be 4 not 8.

Step-by-step explanation:

Sara: The y-intercept is when the x value is 0.

Darrell: Slope of the line is 4 because the b-value goes up by 8 each time and the a-value goes up by 2 each time. Slope is $\frac{y}{x}$, so $\frac{8}{2}$, or 4 simplified.
